The British politician attacked Mr Juncker during his State of the Union speech at the European Parliament.

Slamming his proposals for the future of the EU, Mr Farage said: "Your proposals are reminiscent of regimes of old.

"Indeed, the way you are treating Poland and Hungary already must remind them of living under the Soviet Communists with your attempts to tell them how they should run their own countries.

Mr Farage said Juncker's proposals were echoing the Soviet Communists regimes of old

"All I can say is: thank God we are leaving! You've learned nothing from Brexit."

Farage launched a stinging attack against Mr Juncker and the institution - which was both brutal and witty, single-handedly revealing Junker's speech as an affront to democracy.

Mr Farage lambasted Mr Juncker for proposing an expansion of EU power in the coming years.

He said: “Mr Juncker, that was the most open, honest and most worrying speech I ever heard. What you’re saying is: Brexit has happened, full steam ahead!”

He added that Juncker and his colleagues were appointing powerful unelected people in positions of huge power including “a finance minister who intervenes when he feels it necessary” and plans for “a European army with a more aggressive foreign policy.”

The furious outburst comes after the former Ukip leader told Express.co.uk the European Commission President’s address “will be more about what he doesn’t say” in the lead up to his speech.

He said: “My feeling right now is that this speech will be more about what he doesn’t say than what he does say and I shall say to him that actually by going for more Europe in response to Brexit you actually fuel the populism, as you call it, that led to Brexit.
